To aZZ whom it may concern:

Be it known that I, LOUIS PANZER, of Canandaigua, in the county ofOntario and State of New York, have invented a new and usefulImprovement in Wrenches, which improvement is fully set forth in thefollowing specification and shown in the accompanying drawings.

This invention relates to certain new and useful improvements inwrenches of that class in which are embodied in the one tool a pluralityof implements.

It has for its objects, among others, to provide an improved wrench ofthis general character.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be specifically defined by theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the characters of reference marked thereon, form a part ofthis specification, and in which- Figure 1 is a side elevation of theimproved implement, with parts shown in two positions by full and dottedlines. Fig. 2 is a view of the implement looking in the direction of thearrow a in Fig. 1. Fig. 3 is an end view of the knurled nut employed inconnection with the parts forming the monkey wrench. Fig. at is a viewlooking at the opposite end of said nut. Fig. 5 is an elevation of partsindicated by the arrow 6 in Fig. 1, showing the wire-cutting device.Fig. 6 is a longitudinal section of a part of the body portion of theimplement, taken on the line 0 0 in Fig. 1 looking in the direction ofthe arrow 0. Fig. 7 is a plan view of the upper jaw of the pincers. Fig.8 is a side elevation of parts seen as in Fig. 1, a portion of the leverjaw and the bolt-barrel being vertically and longitudinally sectioned,and a portion of the jaw being broken away. Fig. 9 is a plan of parts atone end of the implement, the parts adjacent the pivot being sectionedand a portion broken away. Figs. 1 and 2 are drawn to a scale ofthree-quarters the full size, the remaining figures being to a scalefull size.

Like characters of reference indicate like parts throughout the severalviews.

Referring to the drawings the members at the one end 1, constitute amonkey wrench. The members at the opposite end 2 serve as Specificationof Letters Patent.

a pipe wrench or the like, a hammer, with a driving head and claws,pincers and a wirecutter.

3 is the body portion; it is formed at one end with the stationary jaw4L, and at the other end with the aws 5 and 6, the hammer head 7 and theclaws 8. The jaws 5 and 6 are relatively fixed and one of them istoothed as seen at 9, the teeth or notches being turned inward or towardthe angle of the jaws as seen in Fig. 1 so as to better hold a rod orpipe.

10 is the movable jaw of the monkey wrench. It is provided with a shank11. which is screw threaded as seen at 12 and this shank is movable in alongitudinal bore or passage 13 in the body portion and through thestationary jaw as shown in Figs. 1 and 6. The longitudinal passage orcavity in the body portion is formed with an enlargement 14 in which isdisposed the nut 15, the periphery of which is roughened or milled asshown for an obvious purpose. The construction of the nut and thiscavity and enlargement is such that the nut which is cylindrical may beremoved from or inserted into the cavity whenever desired. The nut isformed with a longitudinallyprojecting flange 16 as seen in Figs. 1 and3 this projecting flange being in the form of a hollow ring as seen bestin Fig. 3 in which project two tongues 17 extending from the bodyportion upon opposite sides of the cavity, as a means for holding thenut in place. Adjacent the said tongues the material of the body portionis cut away upon opposite sides as seen at 18, the out being practicallyupon a curve as seen by the dotted line at the left of Fig. 6 and aswill be evident also from Fig. 1. At the opposite end of the enlargement14; of the cavity the material of the body portion is cut away as shownat 19 in Figs. 1 and 6, the nut 15 being provided with notches 20 at theouter end so as to clear the two projections 19 when the nut is swunginto place. When being put into place the nut is held in an inclinedposition with relation to the length of the body portion as shown indotted lines in Fig. 2, the left hand or flanged end of the nut beingfirst entered in place, the nut then being swung to place. Thusconnected the out will hold to its place in every position it may assumeexcept when turned so that the notches 20 will exactly coincide with therounded parts 19. When the screwed shank of the movable jaw 10 of themonkey wrench is in its place the nut receiving the same, the nut cannotescape from the body portion. It is to be understood that in order to beremoved the nut must be tilted or brought into its inclined position asindicated by the dotted lines in Fig. 2.

21 and 22 are jaws which constitute a pair of pincers. They are mountedfor movement independent of the body portion and of the jaws 5 and 6.The jaw 21 rocks on a shaft or pin 23 rigid in the body portion 3, whilethe aw 22 rocks or turns on a pivot 24 also rigid in the body portion 3.The said jaws 21 and 22 are pivotally connected by the pivot 25. The jaw22 is provided with a handle 26 for operating it when desired. A flatspring 27 having one end secured to the under side of this handleportion as shown at 28 has its other end bearing against the adjacentedge of the body portion 3 as seen clearly in Fig. 1 and slidingthereupon, serves to hold the pincer jaws 21 and 22 normally open withthe lever or handle 26 swung outward in the position in which it isshown by full lines in Fig. 1. The aw 21 is provided with an elongatedslot 29 in which the pin 23 is received and in which the said pin hasmovement as will be readily understood by reference to Figs. 1 and 7.WVhen the pincers are in use the upper aw 21 will have a longitudinalmovement on the pin 23 as well as rocking on said pin as will be clearlyunderstood by observing the line of the three pivots 24c, 25 and 23, inFig. 1. When the jaws 21 and 22 are forced together by pressing upon thehandle or lever 26, their acting or operating faces meet as indicated bythe dotted lines in Fig. 1. The jaw 22 is formed with a depression orthe like 30 as seen best in Fig. 3, said hole be ing in the rear edge orface of the aw and adapted to receive the pin or reduced end portion 31of a bolt 32 which is mounted to slide longitudinally in a barrel orcasing 33 rigidly affixed to the body portion 3. The bolt is moved by aspring 34 disposed between the inner end of the bolt and the end of thebarrel or casing as shown in Fig. 8 and tending to hold the end of thebolt normally in engagement with the hole on the jaw 22. The object andpurpose of this bolt is to hold the lever 26 down as indicated in dottedlines in Fig. 1 and by full lines in Fig. 8, so that it may be out ofthe way while using the device as a monkey wrench, or a pipe wrench, oras a hammer for driving or pulling nails or the like. The adjacent faceof the body portion, is, as seen in Fig. 1, hollowed out as at 35 toreceive this lever or handle 26 when in the closed position.

One of the fixed jaws of the wrench, preferably the jaw 5 has its endslightly ex; tended as seen at 36 in Figs. 1 and 2 to serve as a screwdriver or the like. The sliding bolt is provided with suitable means, asthe knob or handle 37 movable in a slot 38 in the barrel or casing, bywhich it may be readily moved. The wire cutting mechanism comprises ashear cut 39 as seen in Figs. 1 and One portion is formed in the aw 6and the other 40 in the jaw 22, the operation being as is common in thisform of wire cutters.

Modifications in detail may be resorted to without depart-ing from thespirit of the invention or sacrificing any of its advantages. Forinstance, the head of the pivot or pin 23 is shown as elongated to coverthe slot 29, as seen clearly in Fig. 1, but this is not essential andmay be omitted in some cases. Other like changes in the details ofconstruction I should consider as coming clearly within the scope of myinvention as covered by the appended claims. The devices, aside fromthose forming the wrench, as hereinafter claimed, are for illustrativepurposes only, and form no part of the present invention.

hat is claimed as new is 1. In a wrench, a body portion with astationary jaw, said body portion having a longitudinal cavity andtongues, said cavity being laterally enlarged, a movable aw with athreaded shankreceived in said cavity, and a nut with an annularlongitudinally-projecting hollow flange received in the enlargement ofsaid cavity and within which said tongues engage, said body havinglongitudi nally extending projections at one end of said enlargedportion of the cavity and the nut being provided at its outer end withnotches for cooperation therewith.

2. In a wrench, a body portion with a longitudinal cavity laterallyenlarged, said body portion having at one end of said enlarged portionof the cavity at opposite sides tongues and the wall at the said end ofthe enlarged cavity being cut away upon curved lines, and the oppositeend wall being cut away upon curved lines, and a jaw having a threadedshank received in said cavity and a nut received in the enlarged portionof the cavity and formed at one end with a longitudinally-projectinghollow flange and at the other end with notches.

In witness whereof, I have hereunto set my hand this 16th day of August,1909, in the presence of two subscribing witnesses.
